Thumbs up for ultrasonic record cleaning

@slaw 

Thanks for posting your experiences. Glad it's working for you! I am sure that it will help others to achieve better results.

As for your RO question, I think it is a good one. I used distilled because it has very low concentrations of dissolved minerals, which could conceivably deposit on the record while drying. Dissolved minerals can be measured by conductivity, which is very low for distilled. Specs for RO are harder to come by, and depend on system maintenance, etc.

@terry9,

How does distilled water compare to de-ionized water in this realm?

I’ve read on various threads about a measuring device for mold an so on...I ask because if there's an inexpensive device that might be able to help us determine with more accuracy, a water change in out US cleaners?...  Do you have any thoughts on this?

Thank you.

It depends. First on the quality of distilled water (which is standard), and the sample of RO water (which is not).

If I were doing that measurement, I would try an instrument called a 'megger', which typically reads resistance with the help of a high voltage supply. Since I don't need one, I don't have one, and just bite the bullet and buy pharmacy distilled at $1.50 a gallon. Lazy? Yeah - but that's just me.

Another way to describe how much of an improvement this has made...

I have, waiting for me around 30 newly purchased lps.
I'm finding myself gravitating towards my older lps to hear them like I've never heard them before.This is on my (free day)!

How's that.........?

Is pharmacy distilled a higher standard than Walmart distilled?
